Auto designer Giorgietto Giugiaro is celebrating is 50 years in the business not with cake (well, maybe with cake too) but with a concept Ferrari coupe that he says marks his "great adventure" in the world of car design. That concept is the Ferrari GG50, a compact 2+2 coupe built on a shortened version of the Ferrari 612 Scaglietti platform. It also appears suspiciously similar to the 600 "Imola" (or Testarossa) coupe that's destined to replace the current Ferrari 575M [violin theme builds].
